<u><b>Hoyoung:</b></u> Continued working on packing fractions (PFs).
Corrected PFs with HMS tracking efficiency, by applying it to directly
to the data. This made the PFs really large, which was from using the
efficiency from all triggers. Will redo using efficiency for electron
triggers. <br>
Will look at delta efficiency dependence using scintillators similar to
what Anusha did, which consists of using the scintillator x-planes to
define a "hit" and see its efficiency as a function of x-plane location.<br>

<u><b>Hovhannes/Narbe:</b></u> Obtained minimum energy cut for each
(BigCal) block and implemented in to GEANT. This was to try to smear
the resolution in the MC(~6MeV, compared to~10MeV for data), but so far
the effect was small. Will update the Replay engine in the CVS soon. <br>
<br>
Generating pi0's but did not see very many. Need to run with more
statistics. Working on including secondary particles in ntuples. <br>
<br>
Connected new RAID hard-drive to Octavian for more storage (~4TB)<br>
<br>
<br>
<u><b>Jon:</b></u> Worked some more on double clusters, with looser
threshold cuts <br>

<br>
Looked at parallel asymmetries with recent Replay in CVS. The time
dependence seen before seems to be vanishing. <br>

<u><b>James:</b></u> Looking at particle tracking in front tracker,
extrapolating straight line from hit in calorimeter. Looked with all
energies, then with some Energy cuts/regions. Mapping seen in y appears
to not be correct. Will look at azimuthal and scattering angles for
electrons, look at their energy dependence, and implement slow raster.
Will try rotating from tracker coordinates to lab frame, then
extrapolate to tracker. Resolution will come from higher energies
(>1.3GeV). <br>

<br>
<u><b>Whit:</b></u> Looking at various clustering algorithms to see if
they can be used for defining clusters. <br>
Working on analysis software, including an event viewer with a wrapper
for fortran/PAW using SANE ntuple 1 as a reference.<br>
<br>
<br>
<u><b>Oscar:</b></u> Looking in to GIZMO problem. <br>
